Is Xanthan Gum Water Soluble?

1. Introduction to xanthan gum

As a kind of microbial extracellular polysaccharide with a wide range of functions, xanthan gum, is a popular industrial product produced by Xanthomonas campestris using carbohydrates as the main raw material (such as corn starch) through fermentation engineering. It has unique rheology, good water solubility, stability to heat, acid, and alkali, and good compatibility with various salts. As a thickener, suspending agent, emulsifier, and stabilizer xanthan gum can be widely used in more than 20 industries such as food, petroleum, and medicine. Being able to be applied in various industries, and xanthan gum currently holds the largest production scale in the world as a microbial polysaccharide.

2. Xanthan gum has good water solubility

Since xanthan gum is so widely used, people may wonder is xanthan gum water soluble?

In fact, xanthan gum can quickly dissolve in water and has good water solubility. Moreover, since xanthan gum can also be dissolved in cold water, the use of this product can effectively save complicated processing, and it is convenient for factories to employ it in production. However, due to its strong hydrophilicity, if the water is directly added to xanthan gum and the subsequent stirring is not sufficient, the outer layer of xanthan gum will absorb water and expand into a micelle, which will prevent water from entering the inner layer, thereby affecting its function. Therefore, xanthan gum must be used correctly. To make the full use of xanthan gum, xanthan gum powder, and other dry powder auxiliary materials, such as salt and sugar, should first be mixed well, and then the mixture of xanthan gum powder and auxiliary materials should be slowly added to the stirring water to make an effective solution for later use.
